2003-04-25 paulson 2003-04-25 Changes required by the certified email protocol Public-key model now provides separate signature/encryption keys and also long-term symmetric keys.

1999-03-18 paulson 1999-03-18 exchanged the order of Gets and Notes in datatype event
1999-03-09 paulson 1999-03-09 Added Bella's "Gets" model for Otway_Rees. Also affects some other theories. Changing "spies" to "knows Spy", etc. Retaining the constant "spies" as a translation.
1998-07-24 berghofe 1998-07-24 Adapted to new datatype package.
1997-09-18 paulson 1997-09-18 Global change: lost->bad and sees Spy->spies First change just gives a more sensible name. Second change eliminates the agent parameter of "sees" to simplify definitions and theorems
1997-09-17 paulson 1997-09-17 Spy can see Notes of the compromised agents
1997-07-14 paulson 1997-07-14 Changing "lost" from a parameter of protocol definitions to a constant. Advantages: no "lost" argument everywhere; fewer Vars in subgoals; less need for specially instantiated rules Disadvantage: can no longer prove "Agent_not_see_encrypted_key", but this theorem was never used, and its original proof was also broken the introduction of the "Notes" constructor.
1997-07-11 paulson 1997-07-11 Moving common declarations and proofs from theories "Shared" and "Public" to "Event". NB the original "Event" theory was later renamed "Shared". Addition of the Notes constructor to datatype "event".
